The cam 30 can press the workpiece 100 onto the base plate 10 during rotation.

[0027] Among them, the driving assembly includes a support frame 41, a cylinder 42, a transmission rod 43 and a rotating shaft 44. The support frame 41 is arranged on the bottom plate 10 and is located on one side of the base 20. The cylinder 42 is inclinedly arranged on the support frame 41. The output rod 45 of the cylinder 42 is connected to the transmission rod 43, and the transmission rod 43 is connected to the rotating shaft 44. The rotating shaft 44 penetrates into the base 20 and is connected to the cam 30. The cylinder 42 is used to drive the rotation of the transmission rod 43.

[0028] Here, the cylinder 42 can be controlled electrically or manually, and the manual switch can be combined with the support frame 41 for use.

[0029] Among them, a first slot 431 is arranged above one end of the transmission rod 43, and the end of the output rod 45 is inserted into the slot and is rotatably connected to the transmission rod 43. At the same time, first openings 432 are arranged on both sides of the transmission rod 43.
